Fun fact: if you are in a Bountiful Delve at reset time, you will still get the Bountiful Chest.However, a different Delve will then be your Bountiful one in the zone. I was in Spiral Weave at reset today. My Bountiful in Azj-Kahet is Underkeep.
Whoever wrote this clearly didn't have to deal with Tala and Velo.
